ActiveMethods for test, monitoring and prevention of rock burst—Part 11: Prevention method of destress blasting in coal seam
冲击地压测定、监测与防治方法 第11部分：煤层卸压爆破防治方法
Application Summary AI generated
This standard specifies the technical requirements for using controlled blasting to relieve stress in coal seams as a method to prevent rock bursts. It is applied in underground coal mining operations, particularly in deep or high-stress mines where dynamic rock failures pose safety risks. The standard guides engineers in designing blast parameters, implementing safety measures, and verifying the effectiveness of destress blasting to reduce burst hazards.
